I have public printer for students with Operator hold setting. Jobs are
printed after student come to the printer and tell operator his login. I
would like to automatic delete jobs older than 4 days. However I can't find
any place to set it. I put the command into cron to delete print-jobs-files
from suitable directory from server. This works, but deleted by cron jobs
are still visible boyh in iManager and nwpmw32 utilities and must be
deleted manually - so there is no benefit from cron.
Is there any way to set it?
